Host: fanaticalvps Error: Could Not Determine Fully Qualified Domain Name

Hi. I have a shared host with 5 sites on it. 3 wordpress blogs that almost have nothing on it. 1 xenforo forum that is a year and a 1/2 old and another xenforo that is a couple months old, but inactive. I have all of that on urljet shared hosting. My site is around 3GB total.

Just recently decided to move to an offshore unmanaged vps because of several problems I have with urljet such as I'm not able to use cdns properly with their service and i can't use geoip with them either for digitalpoint's user map.

I have fanaticalvps medium package which is 70gb space, unmetered bandwidth, 700 something ram. but their control panel is confusing in some ways in that yes i can install multiple os that they provide but i keep getting stuck on 'the perfect server' kind of guides because some settings don't match from what i see.

I've been trying to follow The Perfect Server guide for Ubuntu 10.04 for some time now and I keep running into several errors. None of the how-to guides have addressed this issue and the customer support for fanaticalvps answers aren't helping me either.

First issue.

A fellow customer who has the same host as me told me not to touch the network/interfaces file as mentioned in Step 7: Configure The Network.

Because my ip address and host name were already showing but looked different from the sample shown (no server1.example.com type entry) I created a ticket and asked fanaticalvps customer support the following question:

Q: Hello. I'm trying to set the host name. I changed it to rubix but it is asking me for the FQDN. What do I use as the FQDN? For example, in The Perfect Server guide it asks me to update this file. /etc/hosts

A: Where would you be entering this? If it's for DNS you only need to set an A-record for the domain/sub-domain to the IP (hostname makes no difference to this, you can point the domain/sub-domain to the IP with or without the hostname set).
